Haemostatic wound healing sheet

 (clri)

 

Technology/Process Description:

 It is a cost effective, biocompatible as well as biodegradable chemically modified fibrin sheet which is prepared by graft copolymerizing the fibrin film, obtained by drying the purified, bleached and masticated fibrin paste, with a biocompatible, hydrophilic monomer, followed by optional incorporation of drug and subsequent drying and casting into sheet of desired size and shape.

 

The sheet has potential use as a dressing aid in the treatment of various wounds of diversified nature including external injury, cut, burn and even ulcers in animal as well as human being. It prevents loss of electrolyte from the wound site and also prevents any infection in the wound.                                                                                                                                                             The uniqueness of the process lies in the economical utlization of crude fibrin, which is otherwise thrown as waste, thereby making wealth out of waste.

FORMALDEHYDE FREE POLYMERIC SYNTAN

(CLRI)

Technology/Process Description:

The product is essentially a multi-functional organo-polymeric matrix, which is free from formaldehyde. This formaldehyde free polymeric syntan has potential application in chrome tanning of leather as an exhaust aid for chrome. Moreover, it is possible to avoid the pickling operation by using this syntan which emerges as an effective solution for tackling the problem of TDS associated with the effluent of leather processing industry.  Moreover, use of this syntan in tanning enhances the chromium uptake to more than 93%. The presence of this syntan enables a reduction in the offer of filling syntan in wet finishing by about 30-40%. Further, the syntan does not undergo photo-oxidation on ageing. The product provides a very economical as well as eco-friendly option of leather processing.The technology is patent protected and has been commercialized.

CHEMO AUTOTROPHIC ACTIVATED CARBON (CAACO) SYSTEM FOR WASTE WATER TREATMENT

(CLRI)

Technology/Process Description:

 

It is an integrated system of biological and chemical oxidation carried out in a single hybrid reactor packed with activated carbon based redox resin. The process involves anaerobic treatment  of the waste water followed by wet air oxidation using activated carbon which contains Chemo Autotrophic bacteria in immobilized state. Oxygen required for the oxidation of organics is facilitated by supplying air from the bottom of the rector. Since only the stoichiometric quantity of oxygen is supplied for oxidation, utilization of electrical energy is minimized, leading to a saving of electrical power consumption to an extent of 75%, as compared to the conventional aerobic system. The treatment eliminates about 92% of suspended solids, 98%BOD, 85% COD, 100%sulfide, 100% odour with high degree of performance consistency. Another major advantage of the system is that the pH of the processed liquor lies very close to the neutral range, thereby facilitating easy disposal of the processed water.

 

The technology has successfully been implemented in several tanneries for treatment of the tannery effluents. It has also been implemented in multiple textile units ( United Bleachers, Mettupalayam; India Dyeing Pvt. Ltd, Erode; Shuttleweaves, Karur; Celebrity,Madras) Sago units as well as chemical units.  The technology has also been found to be suitable for treating domestic sewage and has already been commercially operational.

RECONSTITUTED COLLAGEN SHEET (RCS)

(CLRI)

Technology/Process Description:

The other Technologies available in this group (collagen based wound healing material) are collagen sheet, collagen sponge, collagen particles, RCS with silver

 

Reconstituted Collagen sheet (RCS) is non-immunogenic, semitransparent cover, which seals the wound while breathing like skin, thereby healing without scar formation. Bovine achilles tendon is solubilised by mechanical, enzymatic and chemical treatment and the pure soluble collagen is purified by successive precipitations at acidic/alkalinne pH. The pure soluble collagen is cut into sheets, cross linked with UV/GTA and sterilised after dry packaging. Unlike collagen sheet, it sticks over the wounds very easily, whereby the progress of wound healing can be monitored easily from outside because of the semi-transparent nature of the sheet. It is an ideal skin substitute for the management of first and second degree of non-infected burns, raw areas caused by release of burns contractures, traumatic loss of skin cover, skin donor sites, amputation sites, chronic skin ulcers, shallow pressure sores and dermal abrasion cases. In third degree burns they are useful as a temporary cover after escharectomy/tangential excision. The RCS can be reconstituted into membrane and sponge material. The technology has already been transferred.

parchment like material

(CLRI)

Technology/Process Description:

The product is essentially a thin, flexible as well as transparent sheet resembling a parchment and is prepared from materials like chrome shavings, trimmings from skin/hide, which are subjected to alkali hydrolysis under controlled conditions. The  paste  is treated with plasticiser/ crosslinker and is finally cast into sheet, which is dried  to get parchment like material. The sheet finds application in the products industry for fabrication of several decorative/fancy items like puppets, lamp shades, chandeliers, wall hangers, table tops etc. The unique feature of the process is that the acidified chrome solution, generated as a byproduct, can be reused in leather processing, thereby suggesting a viable method for chrome recovery/reuse in leather processing industry. Moreover, the material is not prone to insect damage or putrefaction. Thus the process essentially suggests an eco-friendly as well as economical method of utilization of the chrome shavings, which would otherwise add to disposal problem, to make value added products, thereby creating wealth out of waste.
